i OF ST. LOUIS, MISSOURI.

COMBINED CANOPY AND VENTILATOR FOR STOVES.

To all whom it may concern:

, Be it known that I, JOHN l). HAHN, a citi- Zen of the United States,and resident ol' St. Louis, Missouri, have invented certain new and"useful Improvements in a Combined Canopy and Ventilator l'or Stoves,ol' which the following is a specification containing a full, clear, andexact description, reference being had to the accompanying drawings,forming a part hereof.

My invention relates to a canopy or hood particularly adapted for use inconnection with a cook stove or range, and the principal object of myinvention is to construct a simple, inexpensive hood or canopy, which ispositioned immediately over the burners or stove holes, and which hoodor canopy will be the means el' creating a dral't between the top oi thestove on which it is positioned and the chimney flue, thereby carryingoil` all smoke, steam, and odors arising irom the food, or the like,which is being cooked and prepared upon the stove.

A further object oi" my invention is to constructfa stove hood or canopywith a solid rear portion, which normally rests on the rear portion ofthe stove top, and there being a series of slidingl sectional wallsarranged on the rear portion ol' the hood and canopy in such a'manner asthat when drawn -forward,

closed, and all of the smoke and steam arising from the cooking on thestove top will be carried oil' by the natural dral't through the hoodand canopy.

A further object of my invention is to equip a stove hood and canopywith a folding shelf which may be used for holding dishes .and cookingutensils, or whatever desired.

To the above purposes, my invention consists in certain novel featuresof construction andv arrangement oi parts, which will be hereinaftermore fully set forth, pointed out in the claims, and illustrated in theaccompanying drawings, in which Figure 1 is a front elevation of a hoodor canopy of my improved construction, Fig. 2 is a vertical sectiontaken on the line 2--2 of Fig. 1 3 Fig.v 3 is a horizontal section takenon the lineS-S of Fig. 1, with one of the sectionalwalls moved forward;Fig. 4 is an enlarged vertical section taken on the line 4 4 taken onthe line 5 5 of Fig. 1; Fig. 6 is an Specification oi' Letters Patent.

enlarged detail section taken on the line 6--6 of Fig. 1.

Referring by numerals to the accompanying drawings 1 designates the rearwall ol' the hood or canopy, which is vertically disposed adjacent therear edge ol' the stove, and lixed to and extending 'forward from theside edges ol' this rear wall are the side walls 2, the lower portionsol' which are oll such width as that they extend approximately one-halllway toward the front edge o'l` the stove, and the upper ends ol` theseside walls 2 extend l'orward, as designated by 3; and the extremeforward ends oi' the extended upper portions oll said side walls occupypositions imn ediately above the iront corners ol the stove top. Theupper edges ol" the side walls 2 and the upper edge o'l` the rear wall 1are bent to l'orm U-shapcd grooves 4, and projecting inward 'from theseU-shaped bent portions on the sides 2 ol' the hood are horizontally disposed flanges 5.

The top 6 of the hood or canopy is preierably constructed of sheetmetal, and is provided on its lower edge with a dependingl l'lange 7which fits snugly in the U-shaped bent upper edges 4 of the side walls 2and rear wall 1; and the lower edges of the side walls of 'the top 6,immediately adjacent these flanges 7, are bent inward, as designated byS; and the lower edges ol said inwardly bent portions are bent to form.hori- Zontal langes 9, which are arranged directly opposite the ilanges5. rThe lower edge of the front wall of the top 6 is constructed in themanner just described and located on the depending 'llange '7, at thelower edge of said front wall, is a U-shaped rail l0, providedwith ahorizontally disposed flange 11, which is directly opposite the :flange9.

Fixed to the inner faces of the side walls 2 of the hood, at a shortdistance above the bottom of' the hood or canopy, are horizontallydisposed tracks 12, with the inner edges of which are formed integralthe vertically disposed flanges 13. Arranged to slide upon each track12, and immediately against each side wall, is a plate 14, the upperedge of which is bent outward, as designated by 15, and said outwardlybent edge bears directly upon the extending [lange 5. Arranged to slideagainst the inner face of each plate 14 is a plate 16, the top cornersof which are provided with vertically disposed pins 17,

provided on their upper ends with heads 18, and which pins travelbetween the flanges 5 and 9; and the rear edge of each plate 16 iscurved so as to forni a hook 19, which engages a corresponding hook 2G,formed on the forward edge of each plate 14.

Hinged to the inner face and lower portion of the rear wall 1 of thehood is a pair of brackets 21, and hinged to the inner face of said rearwall and adapted to be supported by said bracket 21, is a shelf 22.

My improved stove hood or canopy constructed as herein described ispositioned on top of a stove, and under normal conditions, or wherelight cooking is being done, the sectional walls, comprising the plates14 and 16, occupy positions immediately against the upper portions ofthe side walls 2, as shown in Figl 2.

lli/Then there is an excessive amount of steam, smoke, or odor arisingfrom the food being prepared upon the stove, the forward edges of theplates 16 are engaged and the same are drawn forward g and in so doingthe heads 18 of the pins 17 ride upon the flanges 9 and outwardly bentedges 15 of the plates 14; and when the outer edges of said plates 16have been moved forward to such a degree as that the hooks 19 on therear edges of said plates engage the hooks 2O on the forward edges ofthe plates 14, the pins 17 on the forward ends of said plates 16 willpass between the flanges 9 on the lower front edge of the top 6 and theadjacent flange 11, and said plates 16 are now moved toward one anotherand at right angles to the forwardly moving plates 14 and, as a result,said plates 14 form extensions for the upper portions of the side walls2, and the plates 16 fo ni a front wall which depends from the frontedge of the top 6. Thus the entire space above the top of the stove issubstantially inclosed, and a draft is created through the hood andcanopy to the chimney flue, which draft readily carries off all smoke,steam, and odors from the cooking.

@rdinarily the shelf 22 occupies a vertical position immediatelyTagainst the lower portion of the rear wall 1 of the hood and when it isdesired to use said shelf to support dishes or cooking utensils, saidshelf 22 is elevated, after which the brackets are swung forward tosupport said shelf.

The sliding plates are readily shifted from one position to another, andcooperate with the body of the hood or canopy in form-ing a structure toinclose the space above the burners or stove openings.

The entire apparatus is simple, inexpensive, easily and cheaplymanufactured, can be made in any size to fit different sized stoves andranges, and can be applied to all fornis of gas, gasolene, wood7 coal,or oil stoves.

l claim 1. An attachment for stoves, comprising a hood arranged on topof the rear portion of a stove, which hood comprises a top, side wallsand rear wall, flanges formed integral with said top and with the upperedges of the sides of the body of the hood, and sliding plates havingtheir upper ends supported by said flanges, and which plates are adaptedto be drawn forward to form a front wall for the hood.

2. An attachment for stoves, comprising a hood adapted to be positionedon the rear portion of a stove top and which hood com prises a top, sidewalls and rear wall, a plurality of plates arranged to slide on theupper portion of the side walls of the hood, and which plates when drawnforward form a front wall for the hood, and a shelf arranged on the rearwall of the hood.

3. An attachment for stoves, comprising a hood adapted` to be positionedon the rear portion of a stove top and which hood coinprises a top, sidewalls and rear wall, a plurality of plates arranged toslide onthe upperportion of the side walls of the hood and which plates when drawnforward forni a front wallforthe hood, a shelf hinged to the rear wallof the hood, and brackets hinged to the rear wall of the hood andadapted to swing into position to support the shelf.

1n testimony whereof, l have signed my name to this specification, inpresence of two subscribing witnesses.
